Length-adjustable adapter device for connecting a system part of a plastics processing system to a pipeline
First Claim
1. A length-adjustable adapter device for connecting a plastics melt filtering device to a pipeline, the adapter device comprising:
- a housing connection element having at least one first inner flow duct in a first pipe extension having a reduced outside diameter, said first pipe extension having an external thread;
an adjusting ring element having an internal thread configured to receive the external thread of the first pipe extension of the housing connection element; and
a line connection element configured to connect to the pipeline with a line ring flange and with a second pipe extension having a second inner flow duct,wherein the line ring flange of the line connection element has a multiplicity of passage bores or threaded bores and is rotatable in a receiving groove of the adjusting ring element and is fixed in a form-fitting manner against axially acting forces,wherein the second pipe extension of the line connection element is partially pushed into the at least one first inner flow duct of the housing connection element,wherein the second inner flow duct and the first inner flow duct are configured to overlap, andwherein the adapter device is length-adjustable and configured to have a minimum length when the first and second inner flow ducts have a maximum overlap and a maximum length when the first and second inner flow ducts have a minimum overlap.

Abstract
A length-adjustable adapter device (100) for connecting a plastics melt filtering device (200) to a pipeline (300), having at least a housing connection element (10) which has at least one inner flow duct (13) in a pipe extension (12) which is provided with an external thread (14), an adjusting ring element (20) having an internal thread (24) for receiving the external thread (14) of the pipe extension (12) and a line connection element (30) for connecting to the pipeline (300) with a line ring flange (31) and with a pipe extension (32) having an inner flow duct (33). The line ring flange (31) is rotatable in a receiving groove (23) of the adjusting ring element (20) and is fixed in a form-fitting manner against axially acting forces.
